Okay so i have a problem where it gives me 2 angles which are 64° and 57° . Its asking me to solve 5x+4 to find the missing angle . Idk the answer or what to do ?

I am not sure what you want. Always copy the question exactly. Let's try this:
The sum of the angles of a triangle equal 180 degrees.
180 - 57 - 64 = 59
5x + 4 = 59
5x = 55
x = 11.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
